How do I calculate the Azimuth (angle to north) between two WGS84 coordinates

Question

I have got two WGS84 coordinates, latitude and longitude in degrees. These points are rather close together, e.g. only one metre apart.

Is there an easy way to calcu

Answer 1

This would work only for small differences. Otherwise you can't just "latitudinalDifference / longitudinalDifference".
